US Patent 7326368 - Toxicity reduction of liquid metal using nanoparticles

http://www.freepatentsonline.com/7326368.html

This patent from Japan Nuclear Cycle Development Institute discloses the use of nanoparticles to reduce reactivity and enhance flow resistance of liquid metals used in coolants for nuclear reactors. Claims 1 and 5 reads:

1. A method of reducing reactivity or toxicity in a liquid metal heat transfer medium consisting of the liquid metal itself by dispersing nano-particles selected from the group consisting of metals, alloys and metallic compounds in the liquid metal.

5. A method of enhancing flow resistance in a liquid metal heat transfer medium consisting of the liquid metal itself by dispersing nano-particles selected from the group consisting of metals, alloys and metallic compounds in the liquid metal.
